What does the PlantGrail census measure?
It counts what PlantGrail’s knowledge library covers, as captured on : 4,889 records across 745 plant-name labels. A knowledge record describes a care topic. It is not an observed plant or a measured outcome, so these counts cannot estimate mortality or treatment success.
Problem-text coverage
| Phrase | Matching records |
|---|---|
| root rot | 386 |
| spider mite | 197 |
| overwatering | 183 |
| mealybug | 172 |

Counts use lowercase problem text with hyphens and underscores replaced by spaces, followed by substring matching. Groups overlap; mentions can include conditions to rule out. Do not add the rows or read them as a ranking of causes of death.

Using the guides
Start with your plant and its symptoms, then compare the growing conditions with the checks in its guide. The library’s coverage counts do not tell you which treatment your individual plant needs.
